JS时间格式转换

1.TZ类型的UTC时间转化为本地时间

tz_t_locale = (time: string, time_zone: number) => {
        let T_pos = time?.indexOf('T');
        let Z_pos = time?.indexOf('Z');
        let year_month_day = time?.substr(0,T_pos);
        let hour_minute_second = time?.substr(T_pos+1,Z_pos-T_pos-1);
        time = year_month_day+" "+hour_minute_second;
        return time ?moment(time).subtract(-time_zone, 'hours').local().format('YYYY-MM-DD HH:mm:ss') :'------';
    }

time_zone为时区，中国所在东八区，传8即可。

2.时间戳类型时间转化为本地时间

stamp_t_locale = (time: any) => {
        let date = new Date(time * 1000);
        let year = date.getFullYear();
        let month = (date.getMonth() + 1 < 10 ? `0${date.getMonth() + 1}`: date.getMonth() + 1)
        let day = date.getDate() < 10 ? `0${date.getDate()}` : date.getDate();
        let hours = date.getHours() < 10 ? `0${date.getHours()}` : date.getHours();
        let minutes = date.getMinutes() < 10 ? `0${date.getMinutes()}` : date.getMinutes();
        let seconds = date.getSeconds() < 10 ? `0${date.getSeconds()}` : date.getSeconds();
        let formattedDate = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
        return formattedDate
    }
